The 640 XL is a tribute to six employees who have devoted 40 or more years of service to Buck Knives. In the 1970s, these young men were developing a product for Buck Knives and were an integral part in the move from California to Idaho to set up the new factory some 30 years later. Development of this unique, legacy knife was not rushed and was based on the 124 Frontiersman, a knife they all owned and worked on 40 years ago. A consensus among the six men needed to be met at every detail and aspect. It is created with one of the first steels ever used by Buck Knives, 440C, and custom filework was added to the spine. The handcrafted Elk handle was chosen as a timeless material and accentuated with nickel silver and buffalo spacers. This knife carries a deep-rooted Buck story and will be just as relevant in 40 years as it is today.![]()
